Course description and aims

This course consists of exercises corresponding to the course contents in Mechanics of Materials (MEC.C201) regarding mechanical properties of materials required for machinery strength design and mechanical response of materials making up machinery under external loads. First, students will learn about mechanical properties of materials, stress-strain relationship, and the concepts of allowable stress and safety factor. Next, they will work on exercises illustrating mechanical responses when materials are subjected to tensile, compressive, torsional and bending loads. Finally, they will address practical problems using a method that solves unknown displacement and external load acting on the deformed material based on its elastic strain energy.

Student learning outcomes

At the end of this course, student will be able to:
1) explain the concept of stress and strain in mechanics of materials.
2) solve the stress and strain in tensile, compressive and torsional loading condition.
3) solve the stress and displacement in beam subjected to bending load.
4) express the combined stress state based on essential of elastic mechanics.
5) solve the simple problem in statically indeterminate beam based on the relationship between load and elastic strain energy.
